Various negative ions

Small ions have more beneficial effects on the human body.

You may not know but negative ions floating in the air have different masses.
They are classified into large and small ions depending on the mass of the molecule.

Clinical tests show that small ions have more beneficial effects on the human body than large ions.

Please be careful that some manufacturers give you negative ion count data
which includes both small/large ions, when it should only include small ions.
This happens when it is measured by a simple ion counter which detects small and large ions together.
